Answer:
Timmy can make the electromagnet strong by the following ways
- Using a battery having more voltage and current
- By increasing the number of loops
Explanation:
An electromagnet can be made by having a source of voltage that is a battery or a cell, a conductor, and metal piece. Wrap insulated copper wire tightly around an iron screw or nail before connecting the wire to a battery. Making sure to leave enough of the wire unwound so that it can be attached to the battery. The more wire is wrapped around the nail, the stronger the electromagnet will be. We can make the flux or strength stronger by increasing the voltage and number of loops of wire.
Answer:
C) increase the number of coils of copper he puts around the nail
